Solar data analytical equipment, it is arranged in the front end instrument board of vehicle, connects with Wiener filtering equipment Connect to obtain filtering image；For each pixel in filtering image, by its gray value with presetting Sunlight tonal range is matched, and when its gray value is in default sunlight tonal range, is determined that it is Sunlight pixel；The region that all sunlight pixels in filtering image are formed is divided from filtering image Cut out to obtain each sunlight subgraph；And determine it in filtering figure based on each sunlight subgraph Position as in and calculate it and occupy the area ratio of filtering image；Export each sunlight subgraph point Area ratio corresponding to not corresponding position and difference；

DSP process chips include timing unit；

DSP process chips include memory cell.
